Hello,

After reviewing our records, we've determined that your AdSense account
poses a risk of generating invalid activity. Because we have a
responsibility to protect our AdWords advertisers from inflated costs due
to invalid activity, we've found it necessary to disable your AdSense
account. Your outstanding balance and Google's share of the revenue will
both be fully refunded back to the affected advertisers.

i said okay wow this is really weird. i didn't really freak out so i just linked my youtube account to an older adsense account that i used earlier. I come back the next day and it says my tab is now DISABLED? Why? i never clicked my own ads, never used inappropriate content. everything worked fine. PLEASE someone is there some way to get my tab re-enabled, ive heard of it happening before.
